<p>Not content to ruin the hopes of gamers wanting to upgrade to a Hawaii based AMD GPU now your smart devices are being press ganged into mining crypto-currency.&nbsp; Everything from TVs and fridges through printers, routers and security cameras can be infected with the linux.darlloz worm and will then begin mining for the author of the worm.&nbsp; The worm will even block other infections and has even been monitored patching certain holes in routers to prevent anything else from infecting the device and slowing down the mining computations.&nbsp; <a href="http://www.theinquirer.net/inquirer/news/2335460/the-internet-of-things-is-being-used-to-mine-digital-currency">The Inquirer does have some humourous news about this worm</a>, there are 31,716 separate IP addresses infected but this has manged to raise a mere $196.00 so for the author.</p>

<p>As we have talked about on <a href="http://www.pcper.com/news/Graphics-Cards/Video-Perspective-GPU-Shortages-and-Litecoin-Mining-Discussion">several</a> <a href="http://www.pcper.com/news/Graphics-Cards/Curious-where-all-those-AMD-R9-graphics-cards-are-going">different</a> <a href="http://www.pcper.com/news/General-Tech/AMD-Radeon-R9-290X-Hits-900-Newegg-Thanks-coin">occasions</a>, Altcoin mining (anything that is NOT Bitcoin specifically) is a force on the current GPU market whether we like it or not. Traditionally, Miners have only bought AMD-based GPUs, due to the performance advantage when compared to their NVIDIA competition. However, with continued development of the cudaMiner application over the past few months, NVIDIA cards have been gaining performance in Scrypt mining.</p>
<p>The biggest performance change we&#39;ve seen yet has come with <a href="https://bitcointalk.org/index.php?topic=167229.msg1741471#msg1741471">a new version of cudaMiner released yesterday</a>. This new version (2014-02-18) brings initial support for the Maxwell architecture, which was just released yesterday in the GTX 750 and 750 Ti. With support for Maxwell, mining starts to become a more compelling option with this new NVIDIA GPU.</p>
<p>With the new version of cudaMiner on the reference version of the GTX 750 Ti, we were able to <strong>achieve a hashrate of 263 KH/s,</strong> impressive when you compare it to the performance of the previous generation, Kepler-based GTX 650 Ti, which tops out at about 150KH/s or so.</p>
<p class="rtecenter"><div class = "center-article-image"><a href="/news/General-Tech/NVIDIA-Coin-Mining-Performance-Increases-Maxwell-and-GTX-750-Ti" class="inline-image-link" title="View: IMG_9552.JPG"><img src="/files/imagecache/article_max_width/news/2014-02-19/IMG_9552.JPG" alt="IMG_9552.JPG" title="IMG_9552.JPG" class="pcper-inline" width="602" height="442" /></a></div></p>
<p><a href="http://www.pcper.com/reviews/Graphics-Cards/NVIDIA-GeForce-GTX-750-Ti-Review-Maxwell-Architecture-debuts-150/">As you may know from our full GTX 750 Ti Review</a>,&nbsp; the GM107 overclocks very well. We were able to push our sample to the highest offset configurable of +135 MHz, with an additional 500 MHz added to the memory frequency, and 31 mV bump to the voltage offset. All of this combined to a ~1200 MHz clockspeed while mining, and an additional 40 KH/s or so of performance, <strong>bringing us to just under 300KH/s with the 750 Ti</strong>.</p>
<p class="rtecenter"><div class = "center-article-image"><a href="/news/General-Tech/NVIDIA-Coin-Mining-Performance-Increases-Maxwell-and-GTX-750-Ti" class="inline-image-link" title="View: perf.png"><img src="/files/imagecache/article_max_width/news/2014-02-19/perf.png" alt="perf.png" title="perf.png" class="pcper-inline" width="600" height="678" /></a></div></p>
<p>As we compare the performance of the 750 Ti to AMD GPUs and previous generation NVIDIA GPUs, we start to see how impressive the performance of this card stacks up considering the $150 MSRP. For less than half the price of the GTX 770, and roughly the same price as a R7 260X, you can achieve the same performance.</p>
<p class="rtecenter"><div class = "center-article-image"><a href="/news/General-Tech/NVIDIA-Coin-Mining-Performance-Increases-Maxwell-and-GTX-750-Ti" class="inline-image-link" title="View: power.png"><img src="/files/imagecache/article_max_width/news/2014-02-19/power.png" alt="power.png" title="power.png" class="pcper-inline" width="600" height="677" /></a></div></p>
<p>When we look at power consumption based on the TDP of each card, this comparison only becomes more impressive. At 60W, there is no card that comes close to the performance of the 750 Ti when mining. This means you will spend less to run a 750 Ti than a R7 260X or GTX 770 for roughly the same hash rate.</p>
<p class="rtecenter"><div class = "center-article-image"><a href="/news/General-Tech/NVIDIA-Coin-Mining-Performance-Increases-Maxwell-and-GTX-750-Ti" class="inline-image-link" title="View: perfdollar.png"><img src="/files/imagecache/article_max_width/news/2014-02-19/perfdollar.png" alt="perfdollar.png" title="perfdollar.png" class="pcper-inline" width="600" height="671" /></a></div></p>
<p>Taking a look at the performance per dollar ratings of these graphics cards, we see the two top performers are the AMD R7 260X and our overclocked GTX 750 Ti.</p>
<p class="rtecenter"><div class = "center-article-image"><a href="/news/General-Tech/NVIDIA-Coin-Mining-Performance-Increases-Maxwell-and-GTX-750-Ti" class="inline-image-link" title="View: perfpower.png"><img src="/files/imagecache/article_max_width/news/2014-02-19/perfpower.png" alt="perfpower.png" title="perfpower.png" class="pcper-inline" width="600" height="670" /></a></div></p>
<p>However, when looking at the performance per watt differences of the field, the GTX 750 Ti looks more impressive. While most miners may think they don&#39;t care about power draw, it can help your bottom line. By being able to buy a smaller, less efficient power supply the payoff date for the hardware is moved up. &nbsp;This also bodes well for future Maxwell based graphics cards that we will likely see released later in 2014. &nbsp;</p>

Thanks *coinhttp://www.pcper.com/news/General-Tech/AMD-Radeon-R9-290X-Hits-900-Newegg-Thanks-coin
<div style="padding:1px 10px; background-color: rgba(0, 60, 120, 0.25);">
<p><strong><u>UPDATE (Feb 14th, 11pm ET):</u></strong> As a commenter has pointed out below, suddenly, as if by magic, Newegg has <a href="http://www.kqzyfj.com/click-5682563-10487648?url=http%3A%2F%2Fwww.newegg.com%2FProduct%2FProductList.aspx%3FSubmit%3DENE%26N%3D-1%26IsNodeId%3D1%26Description%3Dr9%2520290x%26bop%3DAnd%26Order%3DPRICE%26PageSize%3D20" target="_blank">lowered prices on the currently in stock R9 290X cards by $200</a>. &nbsp;That means you can currently find them for $699 - only $150 over the expected MSRP. &nbsp;Does that change anything about what we said above or in the video? &nbsp;Not really. &nbsp;It only lowers the severity.</p>
<p>I am curious to know if this was done by Newegg voluntarily due to pressure from news stories such as these, lack of sales at $899 or with some nudging from AMD...</p>
</div>
<p>If you have been keeping up with our podcasts and reviews, you will know that AMD cards are great compute devices for their MSRP. This is something that cryptocurrency applies a value to. Run a sufficient amount of encryption tasks and you are rewarded with newly created tokens (or some fee from validated transactions). Some people seem to think that GPUs are more valuable for that purpose than their MSRP, so retailers raise prices and people still buy them.</p>

<p>Currently, <a href="https://www.youtube.com/watch?v=gllU08ZCygs">the cheapest R9 290X is being sold for $900</a>. This is a 64% increase over AMD&#39;s intended $549 MSRP. They are not even the ones receiving this money!</p>
<p>This shortage also affects other products such as Corsair&#39;s 1200W power supply. Thankfully, only certain components are necessary for mining (mostly GPUs and a lot of power) so at least we are not seeing the shortage spread to RAM, CPUs, APUs, and so forth. We noted a mining kit on Newegg which was powered by a Sempron processor. This line of cheap and low-performance CPUs has not been updated since 2009.</p>

The former was out of stock for over two months after its launch. Those also sometimes strayed from their MSRP, slightly.</p>

<p>Xidax Performance PC, a new boutique PC vendor founded in early 2013 has announced that it is now accepting Bitcoin for payment of its custom-built gaming computers. Reportedly in response to customer demand, Xidax has added bitcoin to its payment options, which are available upon configuring a PC on the website.</p>
<p><div class = "center-article-image"><a href="/news/General-Tech/Boutique-PC-Vendor-Xidax-Now-Accepting-Bitcoin-Payments" class="inline-image-link" title="View: Xidax.jpg"><img src="/files/imagecache/article_max_width/news/2014-01-09/Xidax.jpg" alt="Xidax.jpg" title="Xidax.jpg" class="pcper-inline" width="602" height="349" /></a></div></p>
<p>Xidax Executive Operations Officer Zack Shutt has stated the following in a <a href="http://www.xidax.com/buy-gaming-pc-with-bitcoin">press release</a>:</p>
<blockquote><p>&ldquo;We will do whatever it takes to make custom PC buying easier and give Xidax customers more options,&rdquo; said Shutt. &ldquo;We&rsquo;re intrigued by the growing bitcoin phenomenon and we are happy to provide bitcoin users an easy, secure way to order a custom built PC.&rdquo;</p>
</blockquote>
<p>The bitcoins are handled through a bitcoin payment processor where it can then be converted back to USD (as&nbsp;Xidax is a US-based company). It is interesting to see a PC vendor accepting Bitcoin as it is now possible to purchase an entire, custom built, PC from a major company using funds gathered from mining on a PC (albeit alt-coins converted to BTC or a stockpile of BTC from when GPU mining was still effective). More options are nice, and bitcoin does offer a secure way to pay free of high fees from the likes of Paypal and credit card processors.</p>
<p>What do you think about Xidax accepting bitcoin? Will it add more credibility and/or usefulness to the digital cryptocurrency?</p>

<p><strong>Update:</strong> The main series prize pool was increased to 14 BTC in addition to 1 BTC for the intro match.</p>
<p>So Bitcoins are becoming popular and a legitimate currency. TotalBiscuit decided to create a StarCraft 2 tournament where they are the prize. At the time of the announcement, the 12 Bitcoin prize was valued at about $10,000. Currently, after a little issue in China, it is worth about $7000 to $8000 USD. The English casters are TotalBiscuit and IdrA with several other languages provided including Portuguese and Vietnamese.</p>

<p>The headlining act is Scarlett versus NaNiwa in a best of 7 matchup. Also, they just announced an opening act for a single Bitcoin prize: iNcontroL versus Destiny in a best of 3. The latter pairing are two very comedic personalities. iNcontroL was a prominent player in the Starcraft: Brood War era while Destiny got popular in the StarCraft 2 Beta through Wings of Liberty.</p>
<p>Still no MULEs to mine Bitcoins though.</p>
<p>The stream is <a href="http://www.twitch.tv/totalbiscuit">running now at TotalBiscuit&#39;s Twitch account</a>.</p>

<p>In any event, I thought it might be interesting to extract this 6 minute discussion we had during last nights live streamed podcast about <strong>how the emergence of Litecoin mining operations is driving up prices of GPUs</strong>, particularly the compute-capable R9 290 and R9 290X Hawaii-based cards from AMD.</p>

<p>The price of the GTX 770 is a bit higher than it should be while the GTX 780 and GTX 780 Ti are priced in the same range they have been for the last month or so.&nbsp; The same cannot be said for the AMD cards listed here - the R9 280X is selling for $130 more than its expected MSRP at a minimum but you&#39;ll see quite a few going for much higher on Amazon, <a href="http://www.ebay.com/itm/ASUS-AMD-RADEON-R9-280X-3GB-R9280X-DC2T-3GD5-V2-/231112512974?pt=PCC_Video_TV_Cards&amp;hash=item35cf6115ce" target="_blank">Ebay</a> (<a href="http://techreport.com/news/25760/updated-some-gpus-are-in-short-supply-but-why" target="_blank">thanks TR</a>) and others.&nbsp; The Radeon R9 290 has an MSRP of $399 from AMD but the lowest price we found on Amazon was $499 and anything on Newegg.com is showing at the same price, but sold out.&nbsp; The R9 290X is even more obnoxiously priced when you can find them.</p>

<p>Seasonic (Sea Sonic Electronics) has announced a design win that will see its power supplies used in HashFast&rsquo;s bitcoin mining rigs. The upcoming HashFast mining rigs feature the company&rsquo;s &ldquo;Golden Nonce&rdquo; ASIC(s) and all-in-one water coolers. HashFast has a single ASIC Baby Jet and multi-ASIC Sierra rig. Both units will be available December 15 starting at $2,250 and $6,300 respectively.</p>
<p>The Seasonic power supplies are high efficiency models with Japanese capacitors and at least 80 PLUS Bronze. On the high end, Seasonic has PSUs that are up to 93% efficient. HashFast stated that it chose Seasonic for its mining rigs because of the build quality and efficiency. The Baby Jet and Sierra mining rigs allow users to overclock the ASICs, and the systems can be rather demanding on PSUs.</p>
<p><div class = "center-article-image"><a href="/news/General-Tech/Seasonic-PSUs-Will-Power-HashFast-Bitcoin-Miners" class="inline-image-link" title="View: HashFast Baby Jet BTC Miner.jpg"><img src="/files/imagecache/article_max_width/news/2013-10-21/HashFast%20Baby%20Jet%20BTC%20Miner.jpg" alt="HashFast Baby Jet BTC Miner.jpg" title="HashFast Baby Jet BTC Miner.jpg" class="pcper-inline" width="375" height="500" /></a></div></p>
<p>The Golden Nonce ASIC is a 28nm chip that is rated at 400 GHash/s and 0.65 Watts per Gigahash.</p>
<p>Beyond that, the companies have not gone into specifics. It is good news for Seasonic, and should mean a stable system for bitcoin miners (the 93% efficiency rating is nice as well, as it means less wasted electricity and slightly more bitcoin mining profit).</p>

<p>Earlier this week, the 50BTC reward given to miners that successfully find blocks of Bitcoin transactions was halved to 25BTC. This means that the gross income of miners is now half of what it has been since the cryptocurrency&rsquo;s inception. As a result, many miners &ndash; especially those using graphics cards &ndash; will have to re-evaluate their net earnings to determine if they are still making any profits from mining coins after hardware and electricity costs are taken into consideration.</p>
<p class="rtecenter" style=""><div class = "center-article-image"><a href="/news/General-Tech/Bitcoin-Block-Reward-Halved-25BTC" class="inline-image-link" title="View: Bitcoin Clock.jpg"><img src="/files/imagecache/article_max_width/news/2012-11-28/Bitcoin%20Clock.jpg" alt="Bitcoin Clock.jpg" title="Bitcoin Clock.jpg" class="pcper-inline" width="602" height="588" /></a></div></p>
<p>As an example, when mining bitcoins using a single <a href="http://verrytechnical.com/safely-unlocking-extra-shaders-in-reference-amd-6950-graphics-cards/">shader-unlocked AMD Radeon HD 6950</a> graphics card, I was able to obtain approximately 0.12 BTC per day. Now, because the reward is cut in half, I am able to make about 0.06 BTC per day. Unfortunately, that is approximately the same amount of BTC (when converted to USD) that it costs in electricity to run, negating profits. Technically, according to <a href="http://allchains.info">Allchains.info</a>, I am (just barely) still profitable with a net profit of $0.076 USD per day after electricity costs. As the exchange rate has gone up slightly, it is a bit more than that in actuality but it is still a good estimation of profitability. There are also non-monetary costs associated with mining bitcoins in the form of the extra heat and noise generated by the graphics card being run under load 24/7. And at $0.076 cents a day, it really does not seem worth it anymore. Then again, it does act as a room heater in the winter and it at least subsidizes part of the cost of heating the room (heh) even if it does not pay out much more than it costs to run.</p>
<p>It will be interesting to see how miners react, especially once the colder months are behind us. Some Bitcoin miners have moved on to alternative cryptocurrencies such as Litecoin and Terracoin, however that has caused the difficulty of mining LTC to double without an equal increase in exchange rate which has actually made mining LTC less profitable than mining BTC (d&#39;oh!).</p>
<p class="rtecenter" style=""><div class = "center-article-image"><a href="/news/General-Tech/Bitcoin-Block-Reward-Halved-25BTC" class="inline-image-link" title="View: Screenshot (398).png"><img src="/files/imagecache/article_max_width/news/2012-11-28/Screenshot%20%28398%29.png" alt="Screenshot (398).png" title="Screenshot (398).png" class="pcper-inline" width="602" height="222" /></a></div></p>
<p>The reward halving is not an unexpected event, and, in fact, it has been intentionally executed by the bitcoin developers to prevent inflation. Just as the mining difficulty adjusts every 2016 blocks, every four years the reward is cut in half until mining blocks no longer provides rewards (with the intention that transaction fees will provide all of the incentive to mine from then one). As such, many miners knew about it before hand, and planned accordingly. Some miners sold off their rigs, others (mostly those with free electricity) are continuing to mine, and yet other miners moved to alternative cryptocurrencies.&nbsp;(That&#39;s not to mention those that mine for the purpose of securing the network which is not always a profitable (albeit necessary) pursuit.)</p>
<p>Interestingly, the difficulty of Bitcoin is estimated to <em>increase</em> rather than decrease with the upcoming adjustment despite the reward split and a certain number of users moving away from mining. This may be the result of miners speculating that the price (exchange rate of USD/BTC) will increase and/or that other miners will drop off and the difficulty will begin to decrease at some point. Miners with lage farms of gaphics cards may also be able to hold out despite the block reward halving as they have enough hashing power to keep profits at a worthwile level. While my single card is only making about $18 a month now (versus ~35+), users with more cards can still be seeing sizable returns. So long as profits are there, mining will continue, though newcomers looking to invest in mining rigs are less likely to join in the current climate (seemingly vaporware ASICs notwithstanding). There may also be users that are mining solely for BTC that they will hoard or spend with merchants (like WordPress) that accept bitcoins without concern for exchanging to USD or other national currencies.&nbsp;</p>
<p>In all, there are an astounding number of factors surrounding the block reward halving along with many theories about what will happen as a result of it. At this point, it is still to early to tell, but It will be interesting to see which theories hold true.</p>

<p>A new piece of malware was recently uncovered by anti-virus provider Symantec that seeks to profit from your spare computing cycles. Dubbed <a href="http://www.symantec.com/business/security_response/writeup.jsp?docid=2011-081115-5847-99&amp;tabid=2">Trojan.Badminer</a>, this insidious piece of code is a trojan that (so far) is capable of affecting Windows operating systems from Windows 98 to Windows 7. Once this trojan has been downloaded and executed (usually through an online attack vector via an unpatched bug in flash or java), it proceeds to create a number of files and registry entries.</p>
<p class="rtecenter"><div class = "center-article-image"><a href="/news/General-Tech/New-TrojanBadminer-Malware-Steals-Your-Spare-Processing-Cycles-Make-Criminals-Mone" class="inline-image-link" title="View: bitcointrojan.png"><img src="/files/imagecache/article_max_width/news/2011-08-17/bitcointrojan.png" alt="bitcointrojan.png" title="bitcointrojan.png" class="pcper-inline" width="500" height="300" /></a></div></p>
<p class="rtecenter">It's a trojan infected bitcoin, oh the audacity of malware authors!</p>
<p>After it has propagated throughout the system, it is then able to run one of two mining programs. It will first search for a compatible graphics card, and run Phoenix Miner. However, if a graphics card is not found, it will fall back to RPC miner and instead steal your CPU cycles. &nbsp;The miners then start hashing in search of bitcoin blocks, and if found, will then send the reward money to the attacker&rsquo;s account.</p>
<p>It should be noted that bitcoin mining itself is not inherently bad, and many people run it legitimately. In fact, if you are interested in learning more about bitcoins, we ran an <a href="http://www.pcper.com/reviews/Graphics-Cards/Bitcoin-Currency-and-GPU-Mining-Performance-Comparison">article</a> on them recently. This trojan on the other hand is malicious because it is infecting the user&rsquo;s computer with unwanted code that steals processing cycles from the GPU and CPU to make the attacker money. All these GPU and CPU cycles come at the cost of reduced system responsiveness and electricity, which can add up to a rather large bill, depending on where you live and what hardware the trojan is able to get its hands on.</p>
<p>Right now, Symantec is offering up general tips on keeping users&rsquo; computers free from the infection, including enabling a software firewall (or at least being behind a router with its own firewall that blocks unsolicited incoming connections), running the computer as the lowest level user possible with UAC turned on, and not clicking on unsolicited email attachments or links.</p>
<p>If you are also a bitcoin miner, you may want to further protect yourself by <a href="https://en.bitcoin.it/wiki/Securing_your_wallet">securing your bitcoin wallet</a> in the event that you also accidentally become infected by a trojan that seeks to steal the wallet.dat file (the file that essentially holds all your bitcoin currency).</p>
<p>Stay vigilant folks, and keep an eye out on your system GPU and CPU utilization in addion to using safer computing habits to keep nastly malware like this off of your system. &nbsp;On a more opinionated note, is it just me or have malware authors really hit a new low with this one?</p>

<p>With all the research that Ken did, it turns out that Bitcoin mining will not make you rich overnight and possibly cost you more money to create a bitcoin than you will ever see out of it.&nbsp; Now, <a href="http://slashdot.org/story/11/07/25/1239210/Bitcoin-Is-Not-Anonymous">according to a study linked to at Slashdot</a> it seems that one of the big attractions of Bitcoins is not true.&nbsp; Researchers have found that with enough work and data, Bitcoin purchases are not anonymous.&nbsp; Anonymity was never a major goal for those who first envisioned Bitcoins but it has been touted as a major feature by those who have been mining and spending coins.&nbsp; If that is why you are interested in the process of mining maybe it is a better idea to switch to an @home project.</p>

<blockquote><p>&quot;Researchers from University College Dublin have conducted an analysis of anonymity on Bitcoin, and found it is not inherently anonymous, and that in many cases, users and their transactions can be identified. They use techniques such as context discovery and flow analysis to investigate and visualize an alleged theft of Bitcoins, which, at the time of the theft, had a market value of approximately half a million U.S. dollars.&quot;</p>

<p>Earlier this week we looked at <a href="http://www.pcper.com/reviews/Graphics-Cards/Bitcoin-Currency-and-GPU-Mining-Performance-Comparison">Bitcoin mining performance across a large range of GPUs</a> but we had many requests for estimates on the cost of the power to drive them.&nbsp; At the time we were much more interested in the performance of these configurations but now that we have that information and we started to look at the potential profitability of doing something like this, look at the actual real-world cost of running a mining machine 24 hours a day, 7 days a week became much more important.&nbsp;</p>
<p>This led us to today's update where we will talk about the average cost of power, and thus the average cost of running our 16 different configurations, in 50 different locations across the United States.&nbsp; We got our data from the <a href="http://www.eia.gov/cneaf/electricity/epm/table5_6_b.html">U.S. Energy Information Administration website</a> where they provide average retail prices on electricity divided up by state and by region.&nbsp; For use today, we downloaded the latest XLS&nbsp;file (which has slightly more updated information than the website as of this writing) and started going to work with some simple math.&nbsp;</p>
<p>Here is how your state matches up:</p>

<p class="rteleft">The first graph shows the rates in alphabetical order by state, the second graph in order from the most expensive to the least.&nbsp; First thing we noticed:&nbsp;if you live in Hawaii, I hope you REALLY&nbsp;love the weather.&nbsp; And maybe it's time to look into that whole solar panel thing, huh? &nbsp;Because Hawaii was SO&nbsp;FAR&nbsp;out beyond our other data points, we are going to be leaving it out of our calculations and instead are going to ask residents and those curious to just basically double one of our groupings.</p>

<p><strong>** Update 7/13/11 **</strong>&nbsp;&nbsp;We recently wrote another piece on the <a href="http://www.pcper.com/reviews/Graphics-Cards/Bitcoin-Mining-Update-Power-Usage-Costs-Across-United-States">cost of the power to run our Bitcoin mining operations</a> used in this performance article.&nbsp; Based on the individual prices of electric in all 50 states of the US, we found that the cost of the power to run some cards exceeded the value of the Bitcoin currency based on today's exchange rates.&nbsp; I would <a href="http://www.pcper.com/reviews/Graphics-Cards/Bitcoin-Mining-Update-Power-Usage-Costs-Across-United-States">highly recommend you check out that story as well</a> after giving this performance-based article a thorough reading.&nbsp; <strong>**&nbsp;End Update **</strong></p>
<p>A new virtual currency called Bitcoin has been receiving a great deal of news fanfare, criticism and user adoption. The so called cryptographic currency uses strong encryption methods to eliminate the need for trust when buying and selling goods over the Internet in addition to a peer-to-peer distributed timestamp server that maintains a public record of every transaction to prevent double spending of the electronic currency. The aspect of Bitcoin that has caused the most criticism and recent large rise in growth lies in is its inherent ability to anonymize the real life identities of users (though the transactions themselves are public) and the ability to make money by supporting the Bitcoin network in verifying pending transactions through a process called &ldquo;mining&rdquo; respectively. Privacy, security, cutting out the middle man and making it easy for users to do small casual transactions without fees as well as the ability to be rewarded for helping to secure the network by mining are all selling points (pun intended) of the currency.</p>
<p>When dealing with a more traditional and physical local currency, there is a need to for both parties to trust the currency but not much need to trust each other as handing over cash is fairly straightforward. One does not need to trust the other person as much as if it were a check which could bounce. Once it has changed hands, the buyer can not go and spend that money elsewhere as it is physically gone. Transactions over the Internet; however, greatly reduce the convenience of that local currency, and due to the series of tubes&rsquo; inability to carry cash through the pipes, services like Paypal as well as credit cards and checks are likely to be used in its place. While these replacements are convenient, they also are much riskier than cash as fraudulent charge-backs and disputes are likely to occur, leaving the seller in a bad position. Due to this risk, sellers have to factor a certain percentage of expected fraud into their prices in addition to collecting as much personally identifiable information as possible. Bitcoin seeks to remedy these risks by bringing the convenience of a local currency to the virtual plane with irreversible transactions, a public record of all transactions, and the ability to trust strong cryptography instead of the need for trusting people.</p>
<p class="rtecenter"><div class = "center-article-image"><a href="/reviews/Graphics-Cards/Bitcoin-Currency-and-GPU-Mining-Performance-Comparison" class="inline-image-link" title="View: paymentpal.jpg"><img src="/files/imagecache/article_max_width/review/2011-07-12/paymentpal.jpg" alt="paymentpal.jpg" title="paymentpal.jpg" class="pcper-inline" width="558" height="150" /></a></div></p>
<p>There are a number of security measures inherent in the Bitcoin protocol that assist with these security goals. Foremost, bitcoin uses strong public and private key cryptography to secure coins to a user. Money is handled by a bitcoin wallet, which is a program such as the official bitcoin client that creates public/private key pairs that allow you to send and receive money. You are further able to generate new receiving addresses whenever you want within the client. The wallet.dat file is the record of all your key pairs and thus your bitcoins and contains 100 address/key pairs (though you are able to generate new ones beyond that). Then, to send money one only needs to sign the bitcoin with their private key and send it to the recipient&rsquo;s public key. This creates a chain of transactions that are secured by these public and private key pairs from person to person. Unfortunately this cryptography alone is not able to prevent double spending, meaning that Person A could sign the bitcoin with his private key to Person B, but also could do the same to Person C and so on. This issue is where the peer-to-peer and distributed computing aspect of the bitcoin protocol come into play. By using a peer-to-peer distributed timestamp server, the bitcoin protocol creates a public record of every transaction that prevents double spending of bitcoins. Once the bitcoin has been signed to a public key (receiving address) with the user&rsquo;s private key, and the network confirms this transaction the bitcoins can no longer be spent by Person A as the network has confirmed that the coin belongs to Person B now, and they are the only ones that can spend it using their private key.</p>
